Trench Foot

A condition described in World War I in soldiers in the trenches, whose feet were damp and exposed to near-freezing temperatures for prolonged periods, which caused acral vasoconstriction and heat loss; the resulting ischaemia unchains a vicious cycle of necrosis, endothelial damage, intravascular ‘sludging’ of cells, extravasation of protein and fluid, resulting in increased ischaemia; the prolonged cold is followed by vasodilation, burning pain and paresthesiae with formation of haemorrhagic blebs or gangrene, accompanied by cellulitis, lymphangitis, swelling, thrombophlebitis, and persistent hypersensitivity to cold with secondary Raynaud phenomenon
Management Slow warming of foot; if the tissue is warmed too rapidly, reactive hyperthermia, blistering and possibly thrombosis
